14. Electrical connection
Power supply 230 V / 50 Hz
The programming, control and safety equipment is fully wired
and tested.
You only need to connect the power supply and the external
accessories.
Create a permanent connection for the power supply.
The connection to the mains is made via the standard
plug from the assembly set provided, or alternatively via
permanent connection.
The appliance (IP rating IPX4D) is approved for installation
in the immediate vicinity of a bath or shower (protected area
1 according to DIN VDE 0100). Measures must be taken to
prevent jets of water.
A permanent connection must be used instead of the standard
plug for a power connection in protected area 1
In the case of a permanent connection, install a junction
box on site and connect to the mains via a mains isolator
(e.g. heating system emergency stop switch), which ensures
at least 3 mm contact separation across all poles. Flexible
power cables, min. 3 x 0.75 mm².
No other consumers may be connected to the power cable.
In rooms with a bathtub or shower, the appliance may only be
connected via an RCD.
Installation information, electrical connection
- Isolate the system from the power supply before opening.
- Check that the appliance is isolated from the power
supply.
- Remove the front casing.
- Pivot the front of the control unit forwards.
- Open the rear enclosure cover of the control unit.
- Strip approx. 70 mm of insulation from the exible power
cable 3x0,75 mm

.
- Route the cable through the cable entry M16 in the
appliance base.
- Fit strain relief to the cable using a cable tie.
- Clamp down the relevant cores in the terminal area.
Changing the fuse
Ensure omnipolar isolation of the appliance from the power
supply via the on-site isolator prior to changing a fuse.
Danger due to 'live' electrical components. Never touch
electrical components or contacts if the condensing boiler
has not been isolated from the power supply. This constitutes
a risk to life!
